M-V-7 successfully launched. Nickname is "Hinode"

JAXA started receiving signals from the SOLAR-B at 7:21 a.m. (JST) at the Santiago Station, and from those signals we verified that the SOLAR-B had successfully separated from the launch vehicle and its solar array paddles (PDL) had been normally deployed.

The in-orbit SOLAR-B was given a nickname of "Hinode" (meaning "sunrise.")
